The character of Alan Swann, portrayed by Peter O'Toole in the 1982 film My Favorite Year, was based on Errol Flynn.
The hit song "Errol", by Australian band Australian Crawl, was about him.
The phrase "In like Flynn," stems from his 1942 trial for statutory rape.
The underlying causes of his death were myocardial infarction, coronary thrombosis, coronary atherosclerosis, liver degeneration, liver sclerosis and diverticulitis of the colon.
Though Flynn did most of his own stunts in Against All Flags (1952), he balked at the one involving sliding down through a sail on a rapier blade, which was originated by Douglas Fairbanks in The Black Pirate (1926); it was performed by a stunt double.
Warner Brothers' publicity department tried to claim that he was from Ireland, when he was in fact from Tasmania, the small island state of Australia.
Was tried for statutory rape in 1942 but was acquitted.
When banned from drinking on a film set, he would inject oranges with vodka and eat them during his breaks.
